SLIDING AND SWINGING WINDOW AND SASHES Application filed September 25, 1929. Serial No. 394,935.

This invention relates to new and useful improvements in a sliding and pivotal window.

The invention has for an object the provision of a device of the class mentioned which is of simple durable construction, dependable in use and efiicient in action, and which can be manufactured and sold at a reasonable cost.

The invention proposes a sliding and pivotal window consisting of a conventional frame provided with inner and outer sashes, each sash consisting of a central portion hinged at one side to a slide strip, and means for latching the other side of the central portion to a second slide strip. Said means is of exceptionally eflicient construction and arranged to allow free moving of the central portion when not in line with the second slide strip and providing firm latching when these parts are aligned.

The invention has for an object the provisionof a means for latching the central portion of a window sash to a second slide strip,

of simple construction and also proposes a method for forming of certain parts thereof.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the followingdescription and accompanying drawings, and

to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure Fig. 1 is a front elevational view of a window constructed according to this invention.

Fig. 2 shows the window of Fig. 1 with one of the sashes opened.

Fig. 6 is a fragmentary sectional view taken on the line 66 of Fig. 5. I

Fig. 7 is a perspective view of a bracket used in the top portion of the second slide.

Fig. 8 is a fragmentary perspective view of a metal guide used in the top portion of the central portion of the sash and for cooperation with the bracket in Fig. 7. i

Fig. 9 is a perspective view of a bracket used in the bottom portion of the central portion of the sash.

Fig. 10 is a fragmentary perspective view of a guide strip used in the bottom portion of the second slide strip and in coaction with the bracket shown in Fig. 9. I

Fig. 11 is a front elevational view of a window constructed according to the same invention but of modified form.

Fig. 12 is a horizontal sectional view taken on the line 1212 of Fig. 11.

The sliding and pivotal window consists of a frame 15 of conventional design, an in ner sash 16 and an outer sash 17, each of said, sashes comprising a central portion 18 hinged at one side 19 to a slide strip 20, and a means for latching the other side of the central portion to a second slide strip 21.

The said frame 15 consists of vertical sideforming members 22, a top-forming member 23 and a bottom forming member 24. The side-forming members are of hollow construction clearly shown in Figs. 3 and 4 and are arranged for receiving sash weights 25. The side-forming members are also provided with an outer sash guide strip 26, a central sash guide strip 27 and an inner sash guide strip 28.

The sash weights 25 may be connected to the sash cord 25 or repaired by first removing the vertical strip 25 which are secured to the side-forming members 22.

The said outer sash 17 is slidable between the sash strips 26 and 27. A vertical metal guide strip 29 projects from the guide strip 26 and engages the slide strip of the outer sash. The said inner sash is slidable between the sash strips 27 and 28. The sash strip 27 is provided with a lateral tongue 30 engaging in a groove in the slide strip of the inner sash for guiding purposes.

A latch '31 is mounted on the top slide strip of each of the window sashes and is arranged for latching the sash to the side-forming member. Another latch 82 is arranged upon one of the sashes, on the central portion thereof, and is arranged for latching the sashes together. Each of the latches consists of an inverted U. shaped strip 83 attached upon one member and supporting a bolt 34 connected with a handle 35 limited in movements by a slot 86. A plate 3;? is attached'tothe other of the members to be latched together and is provided with an aperture for receiving the bolt.

f The said means for latching the free side 39 on the slidestri-p; and in the top of the slot 38.. The said bracket is provided with. a dovetailed tapered portionv having its large part at the top and itssmall part at the bottomas clearly shown in Fig. 7'.

A vertical n1etalstrip40 projects from the,

side of the central member and has its top formed with a cut-in slot 41 and the portions onv the sides of theslot bent outwards as illustrated in Fig. 8; so as to. be; engageable in 1 the dovetailed tapered; portion of the brack-.

et 39. When the slide strip 21 is in a lowcred: position and the central: portion of the window sash in a raised position so that the bottom end of the vertical metal strip. is

above the bracket 39, the central portion of the sash may then be lowered and. is free at all timesfor slight lateral play until completely lowered when. the flared portion atthev top of the strip 40' engages the taperedportion of the bracket 39 and firmly holdsthe parts against rattling.

The said means for latching the free side; 'ofthe central portion of each of the sashes to the adjacent slide strip also consists of verticalslot 43 in the central portion extended in from the bottom and terminating about at mid portion, a bracket 44 being attached;

on the central portion and in the bottom of the slot 48. This bracketis similar to bracket 39 but differs in that the small part of the taper is at the top and thev large part is at the bottom as clearly shown in Fig. 9. A- verical metal strip45 projects from the side oftheslidestri-p 21 and is formed at its bottom end with a cut-in portion 46 and the ma.-

terial on the side of this cut is-flaredi outward:

as shown in Fig. 10 for engaging in. the tapered portion ofthe bracket 44.

When the slide strip 21 is in a lowered po:

sition and the central-portion 18o fthe window sash in a raised position so that the bot: tom of the vertical strip 40 is directly over the bracket 39, then the bracket 44 will be directly over the top of the vertical metal strip 45 and upon lowering of the central 7 In the modifiedform of the device illustrated Figs. 11 and 12, a window has been illustrated identical in construction to the 1 one just describe'd difiering only" in that the inner and outer sashes. 16 and 17, respec-' tively, have their central portions 18 made of two sections hinged together at 47. This arrangement permits the outer sections of the. central portions 18;" tobeplaced in a position parallelwith the' plane; of the Window frame as shown in the figures.

While we have. shown and described the preferred embodiment of ourirtventiomit ijs.

to,v be. understood that we-do not limit. our

selves to the precise construction herein, disclosed; and; the rightis; reserved; to all; changes and modifications coming within the scope of the. invention as defined in the appended claims.
